为什么要对纳米粒子表面进行改性?有哪些表面改性方法?Why the surface of the nanoparticles was modified? What are the methods of surface modification? 答:对纳米粒子表面进行改性的目的是对纳米粒子进行有效的分散和保护,从而克服团聚的问题。通常有表面物理改性和化学改性两种方法。1)表面物理改性是指通过范德华...
Iron-oxide nanoparticles are prepared by conjugating biocompatible polymers to an inorganic core of magnetite (Fe3O4) or maghemite (Fe2O3) via an anchoring group, such as an amine or carboxylic acid group. The stability of these NPs can be increased by forming a polymer-based shell around ...
In this review, we describe some of the most interesting and recent advances in nanoparticle-based photoacoustic imaging including inorganic nanoparticles, organic/polymeric nanoparticles, nanoparticle coatings, multimodality imaging, as well as emerging topics in the field. WIREs Nanomed Nanobiotechnol 2017...

For this reason, it is evident that more investigations are urgently required to know the most reliable nanoparticle type, size, concentration, the uptake mode, translocation and movement, toxicity profile, and mode of application to enable its wise application on a large scale for crop improvement...
LFP electrochemical performance at high or low temperature and high voltage is not ideal. LFP nanoparticles are sensitive to air which can undergo significant surface oxidation resulting in a low Coulombic efficiency and poor cycle life.Cathode Active Materials Browse now Learn More What is an LTO...
000 hours. Further, they are highly susceptible to external environments such as moisture and oxygen, and gradually color fade, eventually leading to smears and burn-in on the display. While quantum dots are stable inorganic materials, which makes the lifespan of display more than double that ...
They’re tiny machines that work on the nanoscale, being up to 100,000 times smaller than the width of a human hair. These machines, otherwise known as nanorobotics, are set to augment the human race in unforeseen ways. However, this microscopic technology has remained in the prototype pha...
Zinc sulfide is an inorganic compound, the chemical formula is ZnS, the appearance is white or slightly yellow powder, and the color will become darker when exposed to light. It is stable in dry air, and it will gradually oxidize to zinc su
